80 °C

A mixture of 3,5-dibromo-4-methyl-phenol (11.2 g, 42.1 mmol), 2-iodopropane (8.50 mL, 85.0 mmol), potassium carbonate (17.5 g, 126 mmol), and anhydrous DMF (100 mL) was stirred at 80° C. for 3 hours. After cooling to room temperature, the reaction mixture was partitioned between ether (300 mL) and water (300 mL). The organic phase was separated, washed with brine (2×300 mL), dried over sodium sulfate, and concentrated under vacuum to give 1,3-dibromo-5-isopropoxy-2-methyl-benzene (Cpd A, 12.8 g, 99% yield) as an oil.
